📚 Oligopoly Defined
An oligopoly is a market structure dominated by a few large firms. These firms have significant market power, meaning their decisions about price and output can influence the entire market. Think of the airline industry or the mobile phone carrier market. 📱✈️
🤝 Monopolistic Competition Defined
Monopolistic competition, on the other hand, involves many firms selling differentiated products. These products are similar but not identical, allowing firms to have some control over their prices. Examples include restaurants, clothing stores, and coffee shops. ☕👚

🔑 Key Takeaways
- ⚖️ Number of Firms: Oligopolies have few firms, while monopolistic competition features many.
- 📦 Product Differentiation: Oligopolies may or may not have differentiated products, but monopolistically competitive firms always do.
- 🚧 Barriers to Entry: Oligopolies have high barriers, making it difficult for new firms to enter, whereas monopolistic competition has low barriers.
- 📢 Market Power: Oligopolies possess significant market power, while firms in monopolistic competition have some control over their prices.
- 🎯 Strategic Interdependence: Firms in oligopolies must consider their rivals' actions when making decisions. Monopolistically competitive firms do not need to worry about that as much.
